Went outside to shoot my mk23 today and it was working fine until I would pull the trigger the hammer would strike part #50 and the gas and bb would exit the gun but it seamed like it didn't hit hard enough to make the gun completely cycle. After closely examining the gun, part #50 and #80 fell out of the slid of the gun. Just wondering how to put both peaces back into the gun and somehow tighten it so the peaces no longer fall out.

In my manual it says part #80 is the firing pin spring................. I would ratter not have to ship my gun back to kwa but if you think that putting the peaces back into the gun would be too complicated for me (I'm not too experienced in taking a gbb slide apart) then ill send it in.

Sorry, my bad, it was late...Yes it is the firing pin spring. The fact that they came out would indicate to me a parts failure. If you want to try to repair it yourself that is entirely up to you and your comfort level with the gun. But it could pop out again. If you take the gun apart the warranty will be voided. At this point, assuming you have not done so, then the warranty should be intact so long as the gun was purchased from an official KWA reseller and it is within the 45 day window.

Hey sorry to bother you again gut guess what? I fixed my gun!! Turns out it was an easy fix. I decided to tinker around with my gun today for the last time before I shipped it of to get repaired and I noticed that the rear sight(part#13) was loose so I tightened it and guess what ?! The firing pin (part#50) got locked into place. It all makes sense because it all happened when I adjusted the rear sight.
